Area Controller Coordination for Cross-Jurisdiction Vehicle Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In transport vehicle systems, conveyance instructions for special sections that require passage through another jurisdiction area lead to inefficiencies and increased handling time due to the inability to immediately move transport vehicles within the originating jurisdiction area.
Innovation Solution
The system modifies the conveyance instruction process by having the host controller transmit instructions directly to the area controller of the special section's jurisdiction, allowing it to manage empty transport vehicles within its area for execution, thereby avoiding the need for external control and minimizing movement instructions to other areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conveyance instructions are transmitted to area controllers of other jurisdictions for special sections, then transport vehicles can reach placement units in special sections, but handling time increases and conveyance efficiency deteriorates
Solution Approach 1:
The area controller of the jurisdiction where the transport vehicle is located proactively transmits movement instructions to the area controller of the other jurisdiction before the transport vehicle needs to enter the special section. This preliminary action ensures that the path is cleared and the transport vehicle can move efficiently without waiting for coordination delays.
Solution Approach 2:
The area controller of the origin jurisdiction acts as an intermediary by transmitting movement instructions to the area controller of the other jurisdiction. This intermediary role facilitates coordinated control between jurisdictions, enabling efficient handling of conveyance instructions for special sections while maintaining local management autonomy.
2Ease of operation
If area controllers manage transport vehicles independently within their jurisdictions, then local control is maintained, but conveyance instructions for special sections cannot be handled efficiently
Solution Approach 1:
The system merges the control functions of area controllers by enabling the origin jurisdiction's area controller to transmit movement instructions to the other jurisdiction's area controller. This combining of control capabilities allows efficient handling of special section conveyance while preserving the independent operational autonomy of each area controller within their own jurisdiction.
Solution Approach 2:
Area controllers are designed with multi-functional capability: they can independently manage transport vehicles within their own jurisdictions and also cooperate with other area controllers to handle conveyance instructions for special sections. This universal functionality enables both local control and efficient cross-jurisdictional coordination.
3Adaptability or versatility
If transport vehicles must pass through other jurisdictions to reach special sections, then conveyance to special sections is enabled, but handling time increases
Solution Approach 1:
The area controller of the origin jurisdiction transmits movement instructions to the area controller of the other jurisdiction in advance, before the transport vehicle needs to pass through. This preliminary coordination eliminates waiting time during the actual passage, enabling efficient transit through other jurisdictions to reach special sections.
Solution Approach 2:
The system ensures continuous movement of transport vehicles by pre-coordinating passage through other jurisdictions. The movement instructions are transmitted and executed without interruption, maintaining continuous useful action from origin to destination even when passing through multiple jurisdictions, thereby minimizing total movement time.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances conveyance efficiency and reduces handling time by allowing local management of transport vehicles, ensuring that available vehicles within the jurisdiction can execute conveyance instructions promptly, even for special sections.

AI summary
A transport vehicle system 1 includes a track (4), a plurality of transport vehicles (6), a plurality of placement units (8) configured for each transport vehicle (6) to deliver or receive an article (10) thereto or therefrom, and a plurality of area controllers (50A, 50B, 50C) each configured to receive a conveyance instruction from a host controller (60) and causes a transport vehicle (6) in a jurisdiction area to execute various instructions. The area controller (50B), when having received from the host controller (60) a conveyance instruction destined for one special placement unit (80C) belonging to its own jurisdiction area, transmits to another area controller (50A) a movement instruction to cause an empty transport vehicle (6) to move toward the own jurisdiction area, and also causes an empty transport vehicle (6) that has become available in the own jurisdiction area after transmission of the movement instruction to execute the conveyance instruction.
